Why do I get fat when I drink water?

The weather is getting hotter and hotter, and girls in the streets and alleys are beginning to put on summer clothes. Have you noticed that the effects of clothes on top and behind are very different-some people's bras can create deep grooves under their arms and back, some people have a short waist but already have swimming rings, and some people Under the short sleeves, they reveal their swaying "bat arms". Pinch your arms and feel as soft as cotton; when walking, your thighs and calves shake together.

These conditions all indicate that the muscles are soft and atrophied, and the body fat content is too high. You really have to be careful.

Muscle tightness is linked to diabetes and heart disease

Nowadays, no matter what age, fewer and fewer people have tight muscles. Men don't have time to exercise more, spend more time on the wine table, and even don't care about their increasingly prominent abdomen; women are even less willing to exercise more, saying that they are afraid that the sense of muscle will affect women's beauty. Only after their weight exceeded the obesity standard did they be warned that obesity can bring diabetes and coronary heart disease.

Why do some people get fat when eating the same food, but others don't?

Does muscle tightness have anything to do with diabetes and heart disease? What are the most fundamental measures to prevent these chronic diseases? A research report by the National Academy of Sciences revealed a surprising fact: insulin resistance in skeletal muscles is the root cause of obesity, metabolic syndrome and diabetes.

The researchers divided young subjects of normal weight into two groups: one group had normal insulin sensitivity and the other group had insulin resistance but did not have any chronic disease. The so-called insulin resistance means that because the insulin secreted by the human body after a meal is too inefficient in lowering blood sugar, the blood sugar after a meal cannot drop quickly at the same amount of insulin secretion, and more insulin must be used to complete the task.

There is scientific evidence that "drinking cold water can gain meat"

The two groups of subjects ate exactly the same food, but the researchers found that their physiological responses were very different.

Compared with people with normal insulin responses, insulin resistant people had a 60% reduction in the amount of net muscle glycogen stored in their muscles for use during exercise, while in their livers, the amount of fat synthesized was more than twice that of the other group! At the same time, their plasma triglycerides were 60% higher, while high-density lipoprotein cholesterol was 20% lower. This is really scientific evidence of the so-called "drinking cold water can gain weight."

The researchers concluded that eating the same food has very different metabolic effects on insulin-sensitive people and insulin-resistant people. The former uses most carbohydrates to turn them into energy needed for muscle activity, while the latter uses them to synthesize fat, leading to an increase in triglycerides, adverse changes in blood lipids, and even hardening. Because this early change occurred before abdominal obesity and systemic obesity, researchers believe that this change in skeletal muscle may be a very early stage of metabolic syndrome, obesity, diabetes and coronary heart disease.

Low physical activity, soft muscles, and not excessive weight are also prone to chronic diseases

So, how can we prevent the problem of "skeletal muscle insensitivity to insulin"? How can we strengthen the production function of muscle glycogen? The researchers gave an extremely concise answer: enough physical activity.

Professionals point out that because there is not enough physical activity, over time, skeletal muscle will be "used in and out of use". It is no longer good at working efficiently and can no longer incorporate large amounts of glucose into the blood, resulting in the problem of insulin insensitivity; This problem in turn leads to increased fat synthesis and increased blood lipids. Even if a person is still very young or has not even entered middle age, due to long-term lack of exercise, muscles are soft and strength is reduced, which will lead to obstacles in blood sugar metabolism. High blood sugar after a meal will gradually lead to an increase in the proportion of physical fat, and ultimately lead to the occurrence of chronic diseases.

Studies have found that if a woman has poor muscle strength, her risk of developing diabetes in the future will be greatly increased. Conversely, if diabetics are allowed to actively exercise and enhance muscle strength, their blood sugar control will be significantly improved.

Experts suggest that for people with little physical activity and soft muscles, even if they do not exceed the weight, the risk of diabetes and heart disease will still increase. Exercise early to keep your muscles in a healthy and powerful state. Regardless of men and women, it is not only the key to maintaining a beautiful body shape, but also one of the most fundamental measures to prevent obesity and a variety of chronic diseases.
